Configurable hybrid automatic repeat request feedback types for sidelink communication for 5g or other next generation network

ABSTRACT

Facilitating configurable hybrid automatic repeat request (HARQ) feedback types for new radio sidelink communication can be performed for a 5G wireless network. Based on whether reception of data was successful or not, a reception node can send acknowledgement (ACK) data or negative acknowledgement (NACK) data to a base station using an uplink control signal. Therefore, the feedback data can be used to manage subsequent resource allocation decisions within the 5G wireless network.

RELATED APPLICATION

The subject patent application is a continuation of, and claims priority to U.S. patent application Ser. No. 16/277,442, filed Feb. 15, 2019, and entitled “CONFIGURABLE HYBRID AUTOMATIC REPEAT REQUEST FEEDBACK TYPES FOR SIDELINK COMMUNICATION FOR 5G OR OTHER NEXT GENERATION NETWORK,” the entirety of which application is hereby incorporated by reference herein.

TECHNICAL FIELD

This disclosure relates generally to facilitating configurable hybrid automatic repeat requests (HARQ) feedback types. For example, this disclosure relates to facilitating configurable HARQ feedback types for new radio sidelink communication for a 5G, or other next generation network, air interface.

BACKGROUND

5th generation (5G) wireless systems represent a next major phase of mobile telecommunications standards beyond the current telecommunications standards of 4^(th) generation (4G). Rather than faster peak Internet connection speeds, 5G planning aims at higher capacity than current 4G, allowing a higher number of mobile broadband users per area unit, and allowing consumption of higher or unlimited data quantities. This would enable a large portion of the population to stream high-definition media many hours per day with their mobile devices, when out of reach of wireless fidelity hotspots. 5G research and development also aims at improved support of machine-to-machine communication, also known as the Internet of things, aiming at lower cost, lower battery consumption, and lower latency than 4G equipment.

The above-described background relating to facilitating configurable HARQ feedback types for new radio sidelink communication is merely intended to provide a contextual overview of some current issues, and is not intended to be exhaustive. Other contextual information may become further apparent upon review of the following detailed description.

It should be noted that although various aspects and embodiments have been described herein in the context of 5G, Universal Mobile Telecommunications System (UMTS), and/or Long Term Evolution (LTE), or other next generation networks, the disclosed aspects are not limited to 5G, a UMTS implementation, and/or an LTE implementation as the techniques can also be applied in 3G, 4G or LTE systems. For example, aspects or features of the disclosed embodiments can be exploited in substantially any wireless communication technology. Such wireless communication technologies can include UMTS, Code Division Multiple Access (CDMA), Wi-Fi, Worldwide Interoperability for Microwave Access (WiMAX), General Packet Radio Service (GPRS), Enhanced GPRS, Third Generation Partnership Project (3GPP), LTE, Third Generation Partnership Project 2 (3GPP2) Ultra Mobile Broadband (UMB), High Speed Packet Access (HSPA), Evolved High Speed Packet Access (HSPA+), High-Speed Downlink Packet Access (HSDPA), High-Speed Uplink Packet Access (HSUPA), Zigbee, or another IEEE 802.XX technology. Additionally, substantially all aspects disclosed herein can be exploited in legacy telecommunication technologies.

Described herein are systems, methods, articles of manufacture, and other embodiments or implementations that can facilitate configurable HARQ feedback types for new radio sidelink communication for a 5G network. Facilitating configurable HARQ feedback types for new radio sidelink communication for a 5G network can be implemented in connection with any type of device with a connection to the communications network (e.g., a mobile handset, a computer, a handheld device, etc.) any Internet of things (JOT) device (e.g., toaster, coffee maker, blinds, music players, speakers, etc.), and/or any connected vehicles (cars, airplanes, space rockets, and/or other at least partially automated vehicles (e.g., drones)). In some embodiments the non-limiting term user equipment (UE) is used. It can refer to any type of wireless device that communicates with a radio network node in a cellular or mobile communication system. Examples of UE are target device, device to device (D2D) UE, machine type UE or UE capable of machine to machine (M2M) communication, PDA, Tablet, mobile terminals, smart phone, laptop embedded equipped (LEE), laptop mounted equipment (LME), USB dongles etc. Note that the terms element, elements and antenna ports can be interchangeably used but carry the same meaning in this disclosure. The embodiments are applicable to single carrier as well as to multicarrier (MC) or carrier aggregation (CA) operation of the UE. The term carrier aggregation (CA) is also called (e.g. interchangeably called) “multi-carrier system”, “multi-cell operation”, “multi-carrier operation”, “multi-carrier” transmission and/or reception.

In some embodiments the non-limiting term radio network node or simply network node is used. It can refer to any type of network node that serves UE is connected to other network nodes or network elements or any radio node from where UE receives a signal. Examples of radio network nodes are Node B, base station (BS), multi-standard radio (MSR) node such as MSR BS, eNode B, network controller, radio network controller (RNC), base station controller (BSC), relay, donor node controlling relay, base transceiver station (BTS), access point (AP), transmission points, transmission nodes, RRU, RRH, nodes in distributed antenna system (DAS) etc.

Cloud radio access networks (RAN) can enable the implementation of concepts such as software-defined network (SDN) and network function virtualization (NFV) in 5G networks. This disclosure can facilitate a generic channel state information framework design for a 5G network. Certain embodiments of this disclosure can comprise an SDN controller that can control routing of traffic within the network and between the network and traffic destinations. The SDN controller can be merged with the 5G network architecture to enable service deliveries via open application programming interfaces (“APIs”) and move the network core towards an all internet protocol (“IP”), cloud based, and software driven telecommunications network. The SDN controller can work with, or take the place of policy and charging rules function (“PCRF”) network elements so that policies such as quality of service and traffic management and routing can be synchronized and managed end to end.

To meet the huge demand for data centric applications, 4G standards can be applied 5G, also called new radio (NR) access. 5G networks can comprise the following: data rates of several tens of megabits per second supported for tens of thousands of users; 1 gigabit per second can be offered simultaneously to tens of workers on the same office floor; several hundreds of thousands of simultaneous connections can be supported for massive sensor deployments; spectral efficiency can be enhanced compared to 4G; improved coverage; enhanced signaling efficiency; and reduced latency compared to LTE. In multicarrier system such as OFDM, each subcarrier can occupy bandwidth (e.g., subcarrier spacing). If the carriers use the same bandwidth spacing, then it can be considered a single numerology. However, if the carriers occupy different bandwidth and/or spacing, then it can be considered a multiple numerology.

A multiple (e.g., three) party communication framework for V2X can impose a hierarchical structure in a peer-to-peer network. In particular, in a three-party communication framework, a given node, other than the transmitter and the receiver, can be designated to coordinate radio resource usage. The chosen node, dubbed “local manager”, can be responsible for the scheduling and resource allocation among the nodes it manages. If the local manager is denoted as node-S, the transmitting nodes as node-T, the receiving node as node-R, the scheduling/resource allocation can be centralized at the node-S, while the data transmission is done by different nodes (node-T) in a distributed manner.

In the general framework where a local manager node-S is elected and nodes are reliably covered by node-S, the procedure can be described as follows. The node S can broadcast synchronization signals (e.g., synchronization signal broadcast (SSB), transmission reception signal (TRS)) to its surrounding UEs. The broadcasted information can comprise resource pool information. Other nodes can then sync to node-S and receive the broadcast information. When node-T has a V2X traffic data packet, it can send a scheduling request (SR) to node-S. The SR can comprise the following traffic types: V2X broadcast or multi-cast traffic, V2X unicast traffic that additionally indicate the receiver node, and/or cellular traffic.

Upon receiving the SR, node-S can schedule radio resources. The scheduling decision can be transmitted as downlink control information (DCI) from node-S to node-T and node-R. The DCI can comprise the resource allocation, MCS, precoder, etc. Upon receiving the DCI, node-T can transmit data on the allocated radio resource while node-R receives data on the allocated radio resource.

As depicted in FIG. 2, V2X services can comprise both vehicle-to-infrastructure (V2I) communication between vehicles and gNB or roadside access point units, and vehicle-to-vehicle (V2V) communications, which can be over an existing cellular (Uu) interface or a sidelink (e.g., D2D or PC5) interface. One scenario for sidelink resource allocation is to have the base station (e.g., gNB) perform the resource allocation and receive feedback using cellular signaling and protocols (e.g., mode 1 in 3GPP) as shown in FIG. 3. The base station can send DCI to the transmitting V2X UE (Node-T) indicating the sidelink resources, which can be used. The node-T can then send a sidelink control information (SCI) message along with broadcast, groupcast, and/or unicast data to the receiving V2X UE(s) (Node-R). Based on whether the reception of the data was successful or not, the Node-R can send acknowledgement (ACK) or negative acknowledgement (NACK) feedback to the base station using an uplink control information (UCI), which can be used to manage subsequent resource allocation decisions.

This disclosure allows a network to determine a HARQ procedure according to the available resource and traffic QoS. When the HARQ feedback is sent directly back to the transmitter, the transmitter can begin a HARQ re-transmission autonomously when NAK is received. However, without updated ACK/NAK, the scheduler cannot instantaneously allocate more resources for re-transmission. Thus, the scheduler can take that into account and overbook extra resources for retransmission. Consequently, the transmitter can start to re-transmit immediately. Although the system utilized more resources, the data packet latency is reduced. In an alternate embodiment, the HARQ can be sent directly back to the scheduler. Then, the scheduler can schedule the resource precisely when NAK is received. Consequently, there is no waste on the resource side, but since the NAK needs to go the scheduler first, the retransmission latency can be higher. In this scenario, the system uses less resources but with higher data packet latency. Thus, the proposed configuration HARQ procedure can allow the network to trade-off between the data packet latency and resources.

In one embodiment, described herein is a method comprising receiving, by a first wireless network device comprising a processor from a second wireless network device, resource data representative of a configured resource for a physical sidelink feedback channel to be used by a third wireless network device. The method can comprise receiving, by the first wireless network device, an indication that the physical sidelink feedback channel is associated with a physical sidelink control channel. Additionally, in response to the receiving the indication, the method can comprise transmitting, by the first wireless network device, index data representative of the configured resource to be utilized by the third wireless network device to transmit acknowledgement data, representative of an acknowledgement that the third wireless network device has received the configured resource, via the physical sidelink feedback channel.

According to another embodiment, a first wireless network device can facilitate, configuring a physical uplink control channel resource associated with a physical uplink control channel. Based on the configuring the physical uplink control channel resource, the first wireless network device can comprise associating the physical uplink control channel resource with a physical sidelink control channel resource pool. Additionally, in response to the associating, the first wireless network device can comprise establishing a physical downlink control channel between the first wireless network device and a second wireless network device to facilitate a physical sidelink control channel between the second wireless network device and a third wireless network device.

According to yet another embodiment, described herein is a machine-readable storage medium that can perform the operations comprising configuring a first physical sidelink feedback channel to receive acknowledgement data representative of an acknowledgment from a second wireless network device. The machine-readable storage medium can perform the operations comprising transmitting sidelink control data representative of a resource, to be utilized by the second wireless network device, to a third wireless network device via a physical sidelink control channel. Furthermore, the machine-readable storage medium can perform the operations comprising facilitating transmitting the resource to the second wireless network device via the third wireless network device in response to the transmitting the sidelink control data.

These and other embodiments or implementations are described in more detail below with reference to the drawings.

Referring now to FIG. 1, illustrated is an example wireless communication system 100 in accordance with various aspects and embodiments of the subject disclosure. In one or more embodiments, system 100 can comprise one or more user equipment UEs 102, 104. The non-limiting term user equipment can refer to any type of device that can communicate with a network node in a cellular or mobile communication system. A UE can have one or more antenna panels having vertical and horizontal elements. Examples of a UE comprise a target device, device to device (D2D) UE, machine type UE or UE capable of machine to machine (M2M) communications, personal digital assistant (PDA), tablet, mobile terminals, smart phone, laptop mounted equipment (LME), universal serial bus (USB) dongles enabled for mobile communications, a computer having mobile capabilities, a mobile device such as cellular phone, a laptop having laptop embedded equipment (LEE, such as a mobile broadband adapter), a tablet computer having a mobile broadband adapter, a wearable device, a virtual reality (VR) device, a heads-up display (HUD) device, a smart car, a machine-type communication (MTC) device, and the like. User equipment UE 102 can also comprise IOT devices that communicate wirelessly.

In various embodiments, system 100 is or comprises a wireless communication network serviced by one or more wireless communication network providers. In example embodiments, a UE 102 can be communicatively coupled to the wireless communication network via a network node 106. The network node (e.g., network node device) can communicate with user equipment (UE), thus providing connectivity between the UE and the wider cellular network. The UE 102 can send transmission type recommendation data to the network node 106. The transmission type recommendation data can comprise a recommendation to transmit data via a closed loop MIMO mode and/or a rank-1 precoder mode.

A network node can have a cabinet and other protected enclosures, an antenna mast, and multiple antennas for performing various transmission operations (e.g., MIMO operations). Network nodes can serve several cells, also called sectors, depending on the configuration and type of antenna. In example embodiments, the UE 102 can send and/or receive communication data via a wireless link to the network node 106. The dashed arrow lines from the network node 106 to the UE 102 represent downlink (DL) communications and the solid arrow lines from the UE 102 to the network nodes 106 represents an uplink (UL) communication.

System 100 can further include one or more communication service provider networks 108 that facilitate providing wireless communication services to various UEs, including UE 102, via the network node 106 and/or various additional network devices (not shown) included in the one or more communication service provider networks 108. The one or more communication service provider networks 108 can include various types of disparate networks, including but not limited to: cellular networks, femto networks, picocell networks, microcell networks, internet protocol (IP) networks Wi-Fi service networks, broadband service network, enterprise networks, cloud based networks, and the like. For example, in at least one implementation, system 100 can be or include a large scale wireless communication network that spans various geographic areas. According to this implementation, the one or more communication service provider networks 108 can be or include the wireless communication network and/or various additional devices and components of the wireless communication network (e.g., additional network devices and cell, additional UEs, network server devices, etc.). The network node 106 can be connected to the one or more communication service provider networks 108 via one or more backhaul links. For example, the one or more backhaul links can comprise wired link components, such as a T1/E1 phone line, a digital subscriber line (DSL) (e.g., either synchronous or asynchronous), an asymmetric DSL (ADSL), an optical fiber backbone, a coaxial cable, and the like. The one or more backhaul links can also include wireless link components, such as but not limited to, line-of-sight (LOS) or non-LOS links which can include terrestrial air-interfaces or deep space links (e.g., satellite communication links for navigation).

Wireless communication system 100 can employ various cellular systems, technologies, and modulation modes to facilitate wireless radio communications between devices (e.g., the UE 102 and the network node 106). While example embodiments might be described for 5G new radio (NR) systems, the embodiments can be applicable to any radio access technology (RAT) or multi-RAT system where the UE operates using multiple carriers e.g. LTE FDD/TDD, GSM/GERAN, CDMA2000 etc.

For example, system 100 can operate in accordance with global system for mobile communications (GSM), universal mobile telecommunications service (UMTS), long term evolution (LTE), LTE frequency division duplexing (LTE FDD, LTE time division duplexing (TDD), high speed packet access (HSPA), code division multiple access (CDMA), wideband CDMA (WCMDA), CDMA2000, time division multiple access (TDMA), frequency division multiple access (FDMA), multi-carrier code division multiple access (MC-CDMA), single-carrier code division multiple access (SC-CDMA), single-carrier FDMA (SC-FDMA), orthogonal frequency division multiplexing (OFDM), discrete Fourier transform spread OFDM (DFT-spread OFDM) single carrier FDMA (SC-FDMA), Filter bank based multi-carrier (FBMC), zero tail DFT-spread-OFDM (ZT DFT-s-OFDM), generalized frequency division multiplexing (GFDM), fixed mobile convergence (FMC), universal fixed mobile convergence (UFMC), unique word OFDM (UW-OFDM), unique word DFT-spread OFDM (UW DFT-Spread-OFDM), cyclic prefix OFDM CP-OFDM, resource-block-filtered OFDM, Wi Fi, WLAN, WiMax, and the like. However, various features and functionalities of system 100 are particularly described wherein the devices (e.g., the UEs 102 and the network device 106) of system 100 are configured to communicate wireless signals using one or more multi carrier modulation schemes, wherein data symbols can be transmitted simultaneously over multiple frequency subcarriers (e.g., OFDM, CP-OFDM, DFT-spread OFMD, UFMC, FMBC, etc.). The embodiments are applicable to single carrier as well as to multicarrier (MC) or carrier aggregation (CA) operation of the UE. The term carrier aggregation (CA) is also called (e.g. interchangeably called) “multi-carrier system”, “multi-cell operation”, “multi-carrier operation”, “multi-carrier” transmission and/or reception. Note that some embodiments are also applicable for Multi RAB (radio bearers) on some carriers (that is data plus speech is simultaneously scheduled).

In various embodiments, system 100 can be configured to provide and employ 5G wireless networking features and functionalities. 5G wireless communication networks are expected to fulfill the demand of exponentially increasing data traffic and to allow people and machines to enjoy gigabit data rates with virtually zero latency. Compared to 4G, 5G supports more diverse traffic scenarios. For example, in addition to the various types of data communication between conventional UEs (e.g., phones, smartphones, tablets, PCs, televisions, Internet enabled televisions, etc.) supported by 4G networks, 5G networks can be employed to support data communication between smart cars in association with driverless car environments, as well as machine type communications (MTCs). Considering the drastic different communication needs of these different traffic scenarios, the ability to dynamically configure waveform parameters based on traffic scenarios while retaining the benefits of multi carrier modulation schemes (e.g., OFDM and related schemes) can provide a significant contribution to the high speed/capacity and low latency demands of 5G networks. With waveforms that split the bandwidth into several sub-bands, different types of services can be accommodated in different sub-bands with the most suitable waveform and numerology, leading to an improved spectrum utilization for 5G networks.

To meet the demand for data centric applications, features of proposed 5G networks may comprise: increased peak bit rate (e.g., 20 Gbps), larger data volume per unit area (e.g., high system spectral efficiency—for example about 3.5 times that of spectral efficiency of long term evolution (LTE) systems), high capacity that allows more device connectivity both concurrently and instantaneously, lower battery/power consumption (which reduces energy and consumption costs), better connectivity regardless of the geographic region in which a user is located, a larger numbers of devices, lower infrastructural development costs, and higher reliability of the communications. Thus, 5G networks may allow for: data rates of several tens of megabits per second should be supported for tens of thousands of users, 1 gigabit per second to be offered simultaneously to tens of workers on the same office floor, for example; several hundreds of thousands of simultaneous connections to be supported for massive sensor deployments; improved coverage, enhanced signaling efficiency; reduced latency compared to LTE.

The upcoming 5G access network may utilize higher frequencies (e.g., >6 GHz) to aid in increasing capacity. Currently, much of the millimeter wave (mmWave) spectrum, the band of spectrum between 30 gigahertz (Ghz) and 300 Ghz is underutilized. The millimeter waves have shorter wavelengths that range from 10 millimeters to 1 millimeter, and these mmWave signals experience severe path loss, penetration loss, and fading. However, the shorter wavelength at mmWave frequencies also allows more antennas to be packed in the same physical dimension, which allows for large-scale spatial multiplexing and highly directional beamforming.

Performance can be improved if both the transmitter and the receiver are equipped with multiple antennas. Multi-antenna techniques can significantly increase the data rates and reliability of a wireless communication system. The use of multiple input multiple output (MIMO) techniques, which was introduced in the third-generation partnership project (3GPP) and has been in use (including with LTE), is a multi-antenna technique that can improve the spectral efficiency of transmissions, thereby significantly boosting the overall data carrying capacity of wireless systems. The use of multiple-input multiple-output (MIMO) techniques can improve mmWave communications, and has been widely recognized a potentially important component for access networks operating in higher frequencies. MIMO can be used for achieving diversity gain, spatial multiplexing gain and beamforming gain. For these reasons, MIMO systems are an important part of the 3rd and 4th generation wireless systems, and are planned for use in 5G systems.

Referring now to FIG. 2, illustrated is an example schematic system block diagram of a V2X communication 200 according to one or more embodiments. As depicted in FIG. 2, V2X services can comprise both vehicle-to-infrastructure (V2I) communication between vehicles 202 ₄ 202 ₁ and gNB 106 or roadside access point units, and vehicle-to-vehicle (V2V) 202 ₁, 202 ₂, 202 ₃, 202 ₄ communications, which can be over an existing cellular (Uu) interface or a sidelink (e.g., D2D or PC5) interface.

Referring now to FIG. 3, illustrated is an example schematic system block diagram of a V2X communication comprising downlink control information according to one or more embodiments. One scenario for sidelink resource allocation, the base station (e.g., gNB 106) can perform the resource allocation and receive feedback using cellular signaling and protocols (e.g., mode 1 in 3GPP) as shown in FIG. 3. The base station (e.g., gNB 106) can send DCI to the transmitting V2X UE (e.g., node-T 302) indicating the sidelink resources, which can be used. The node-T 302 can then send a sidelink control information (SCI) message along with broadcast, groupcast, and/or unicast data to the receiving V2X UE(s) (e.g., node-R 304). Based on whether the reception of the data was successful or not, the node-R 304 can send acknowledgement (ACK) or negative acknowledgement (NACK) feedback to the base station (e.g., gNB 106) using an uplink control information (UCI), which can be used to manage subsequent resource allocation decisions.

Referring now to FIG. 4, illustrated is an example schematic system block diagram of a V2X communication 400 comprising a local manager 402 according to one or more embodiments. In another embodiment, sidelink resource allocation can have one V2X UE (e.g., the local manager 402) to schedule another instead of a base station or other infrastructure node (e.g., mode 2D in 3GPP). To achieve a three-party communication system, a UE can be appointed as a V2X local manager 402, which can coordinate the resources used by other associated transmitting UEs (e.g., node-T 302) and receiving UEs (e.g., node-R 304) as in shown in FIG. 4.

Both mode-1 and mode-2D have advantages in terms of network control and overhead, respectively. Instead of semi-statically configuring one option over another, it can be beneficial for the network to more dynamically control resource allocation decisions made by the local manager using a network-assisted approach, including the configuration of HARQ feedback between either the scheduling or transmitting nodes(s).

Referring now to FIG. 5 illustrates an example schematic system block diagram of a V2X communication 500 comprising HARQ feedback being transmitted to a transmitter device according to one or more embodiments. A configurable HARQ procedure can facilitate V2X communication. For example, a network can directly configure the UE with destination information of where the HARQ feedback shall be sent. In one example, the HARQ feedback (data) can be sent back to the transmitter node 302, directly. The network can configure a resource for a physical sidelink feedback channel (PSFCH) for HARQ. Inside of the configured PSFCH resource, the index of PSFCH can be determined by: 1) the PSFCH resource can be associated to the allocated resource for a physical sidelink control channel (PSCCH), or 2) the sidelink control information (SCI) provided by the scheduler node 502 can include an index to identify the resources to send to the PSFCH from the set of configured resources at the transmitter node 302 and receiver nodes 304. In particular, the PSFCH destination can be configured at the data transmitter node 304, and a destination identification (ID) can be used to scramble the PSFCH. Additionally, the path loss estimation for power control can be based on the estimated path loss between the transmitter node 302 and the receiver node 304. For example, the receive node 304 can receive a signal in a manner that the receiver node 304 can decode the signal. However, the system should not send the signal out with too much transmission power to over protect the signal because that can create interference to other user devices. Thus, the transmission power can be calculated based on the path loss between the receiver node 304 and the destination node based on where the feedback is to be sent. Then, the path loss between the receiver and the final destination node (e.g., transmitter node, scheduler node, gNB, etc.) for feedback can be used.

Referring now to FIG. 6, illustrated is an example schematic system block diagram of a V2X communication 600 comprising HARQ feedback being transmitted to a scheduler network node device according to one or more embodiments. HARQ feedback can also be sent back to the scheduler node. However, the procedure and signaling can depend on which resource allocation mode is being used by the network and the V2X UEs. If it is mode-1 (e.g., base station configured resource), then the network node (e.g., gNB 106) can configure a physical uplink control channel (PUCCH) resource for HARQ feedback as depicted in FIG. 6. A PUCCH resource can be associated to the corresponding PSCCH resource pool. In addition, a downlink control channel (DCI), which can be used to schedule the PSSCH, can also include an index to identify the index of the PUCCH in the PUCCH resource for carrying HARQ feedback from the set of configured resources. Additionally, the power control scheme can use the path loss between the receiver and the base-station.

Referring now to FIG. 7, illustrated is an example schematic system block diagram of a V2X communication 700 comprising HARQ feedback being transmitted to a scheduler node 502 user equipment device according to one or more embodiments. In a mode-2d configuration (e.g., another UE schedules the resources), the network can configure the PSFCH for the feedback with the destination ID set to be the scheduler node 502 and not the transmitting UE 302 as in type-1 as depicted in FIG. 7 Also, the SCI, which is used for the scheduler node 502 to schedule resources, can comprise an index to identify a particular PSFCH, similar to that of type-1 feedback. In this case, the power control can be based on the path loss between the scheduler node 502 and the receiver UE 304.

Referring now to FIG. 8, illustrated is an example flow diagram for a method for configurable hybrid automatic repeat requests for a 5G network according to one or more embodiments. At element 800, a method can comprise receiving, by a first wireless network device (e.g., transmitter node 302) from a second wireless network device (e.g., scheduler node 502), resource data representative of a configured resource for a physical sidelink feedback channel to be used by a third wireless network device (e.g., receiver node 304). At element 802, the method can comprise receiving (e.g., via the transmitter node 302) an indication that the physical sidelink feedback channel is associated with a physical sidelink control channel. Additionally, in response to the receiving the indication, at element 804, the method can comprise transmitting (e.g., via the transmitter node 302), index data representative of the configured resource to be utilized by the third wireless network device (e.g., receiver node 304) to transmit acknowledgement data, representative of an acknowledgement that the third wireless network device (e.g., receiver node 304) has received the configured resource, via the physical sidelink feedback channel.

At element 900, the first wireless network device (e.g., gNB 106) can facilitate, configuring a physical uplink control channel resource associated with a physical uplink control channel. Based on the configuring the physical uplink control channel resource, at element 902, the first wireless network device (e.g., gNB 106) can comprise associating the physical uplink control channel resource with a physical sidelink control channel resource pool. Additionally, in response to the associating, at element 904, the first wireless network device (e.g., gNB 106) can establish a physical downlink control channel between the first wireless network device (e.g., gNB 106) and a second wireless network device (e.g., the transmitter node 302) to facilitate a physical sidelink control channel between the second wireless network device (e.g., the transmitter node 302) and a third wireless network device (e.g., the receiver node 304).

Furthermore, at element 1004, the machine-readable storage medium can perform the operations comprising facilitating transmitting the resource to the second wireless network device (e.g., the receiver node 304) via the third wireless network device (e.g., the transmitter node 302) in response to the transmitting the sidelink control data.
